"SIP ON THIS: Not your dad's water bottle-- this one's stylish and slender and keeps your drink icy-cold fro 24 hours.  Hot colors such as flamingo and blackboard perk you up during marathon hot yoga sessions.  SO COOL: A double- layer BPA free stainless-steel  insulation system works like a thermos.  LOVE: Ten percent of proceeds go to WaterAid charities in Africa and India."
